Dell to be replaced on major stock indexes

Two very different companies are scheduled to replace Dell Inc. on prominent stock indexes after the company is taken private this month.

McGraw-Hill’s S&P Dow Jones Indices has brought in two stocks to replace the outgoing Dell Inc. after the close of trading on Oct. 28.

Switzerland-based drilling rig company Transocean Ltd. (NYSE: RIG) — which has its U.S. operational headquarters in Houston — will replace Dell on the S&P MidCap 500. Transocean will also be added to the S&P 500 Global Industry Classification Standard’s oil and gas sub-industry index.

New York-based Marsh & McLennan Companies Inc. (NYSE: MMC ) will take Dell’s position on the S&P Global 100.

Round Rock-based Dell is the parent company of Plano-based Dell Services, which employs several thousand workers in the Collin County city. It employs 14,000 workers in Central Texas, and is being taken private after shareholders agreed to a $24.8 billion buyout from an investor group led by CEO Michael Dell and Silver Lake Partners. It comes 25 years after Dell completed its initial public offering.

Michael Dell has said the company needed to be taken private to refashion its business model beyond personal computers to a full-service technology company.
